Booked to go to Disneyland Paris through Disney. Do we need to fill out Advanced Passenger Info online before we go?

Their website says do it at check-in, but everyone else seems to need it at least 24 hours before so I've asked then on Facebook ( I couldn't find an email address online and it was that or register to follow them on Twotter [technophobe]). I'm only worried because a tv programme last week featured a couple who were turned back at check-in because they didn't do it and I don't want a hysterical toddler if that happens to us!

As the title says we are booked to go to Disneyland Paris in just over a week. Booked through Disney and flying into Charles De Gaulle. Haven't heard anything from them about completing Advanced Passenger Info online, but am worried. Can anyone confirm if we have to do this?
